The note drew widespread condemnation in Britain after it was posted on social media by a local paramedic mentor and the local police commander said a 26-year-old woman had been arrested for public order offences.

"Emergency Services must be able to carry out their roles without fear of abuse/intimidation of any kind," Chief Inspector John Owen wrote on Twitter.

"To avoid any confusion, the arrest relates to matters of verbal abuse that could constitute an offence under the Public Order Act. It does not relate solely to the note."
